FPGA, short for Field-Programmable Gate Array is a semiconductor device that can be programmed on-site according to user needs FPGA differs from traditional ASICs (Application-Specific Integrated Circuits) in that it offers high flexibility and reconfigurability, enabling different logic functions to be implemented by modifying software code without changing the hardware circuit. It is like a … Read more
What is an FPGA Chip Integrated circuit chips include two main categories: digital chips and analog chips. Digital chips can be further divided into memory chips and logic chips. The logic chips we are familiar with generally include general-purpose processor chips such as CPUs, GPUs, DSPs, as well as Application-Specific Integrated Circuits (ASICs). FPGA (Field … Read more
This article aims to validate the usage of the STM32 SPI interface using the W25Q16 storage chip. ●About Flash Chips 1. When writing to flash, it can only change from 1 to 0; during erasure, all bits become 1. 2. The minimum write unit for flash is a page; individual bytes cannot be written. 3. … Read more
Introduction Since both the Arduino controlling the lead screw and the board controlling the servo only have one UART, they need to communicate with each other, and also with the Raspberry Pi. Therefore, the number of UARTs is insufficient. Thus, I created a UART Data Manager using the STM32F103 chip, which has three UARTs: USART1~3. … Read more
0 Preface The previous article introduced how to use STM32CubeIDE to create a new project and its features. This article will continue to explain how to configure the project, which is also a very important step. 1 Introduction to the Configuration Interface (STM32CubeMX Interface) The project configuration is mainly operated through the original STM32CubeMX tool. … Read more
01 Introduction In the development of embedded systems based on STM32 microcontrollers, GPIO (General Purpose Input/Output) control is one of the most fundamental and common operations. By using the STM32 HAL library, configuring and controlling GPIO can be done easily. This article will demonstrate how to use the STM32 HAL library for GPIO control and … Read more

The STM32Cube ecosystem is a software ecosystem created by ST for STM32 developers, making it a powerful tool for embedded development. To enhance the usability of the STM32 series microcontrollers, which are … Read more
1. Introduction When learning about the 51 microcontroller, we often use the combination of Keil and Proteus for experiments. This simulation saves us a lot of hardware and time costs, allowing us to visually observe the execution process of the code. However, when switching to the STM32 series microcontrollers, Proteus is obviously not supported, but … Read more
This tutorial series will start from the most basic theories and practices, detailing how to build the STM32F103C8T6 minimum system. The article will divide the minimum system into several modules for sequential introduction, thoroughly analyzing the circuit topology and the role of each component in the circuit along with reasons for their selection. This ensures … Read more
Introduction The STM32 series chips are developed based on the Cortex-M3 core. They adopt the industry-leading Cortex-M3 core architecture, utilizing Harvard architecture and the Thumb-2 instruction set. They can achieve 32-bit performance with a 16-bit code density. Additionally, with single-cycle multiplication instructions, hardware division instructions, and a built-in fast interrupt controller, STM32 chips can run … Read more
